SAUTER 2-Way Flanged Control Valve – DN80, PN16, Kvs 100 m³/h, Equal-Percentage Characteristic

General
The SAUTER VQE080F300 is a heavy-duty, 2-way flanged control valve designed for continuous regulation of cold water, hot water and low-pressure steam in closed-loop systems. With a DN80 nominal diameter, PN16 pressure rating and Kvs value of 100 m³/h, it provides reliable flow control for industrial heating, cooling and HVAC applications.

The valve features an equal-percentage flow characteristic, a grey cast-iron body and seat, stainless-steel spindle and plug, and a maintenance-free stuffing box with double EPDM O-ring seals. It is designed for operation with compatible SAUTER electric actuators, supporting accurate fluid-flow regulation in industrial installations.
